HELPFUL HINTS TO HOG RAISERS 

By C. M. VESTAL 



The swine industry of the Pacific Coast states recently rose to the 
most secure position in its history, when by an agreement the United 
States Food Administration and the packers stabilized the prices of 
market hogs. The agreement reads as follows : 

The food administration deems it imperative that steps be taken to increase 
hog production on the Pacific Coast. In order that producers may have confidence 
that pigs farrowed this spring may be marketed at a fair price, the administration 
hereby adopts the following minimum policy for the period during which similar 
minimums are in force in the Middle West; the average price of packing hogs 
bought by packers at the terminal points of San Francisco, Los Angeles, Portland, 
Oakland, San Diego, Seattle, South San Francisco, Spokane and Sacramento will 
not be less than 1 cent under the food administration minimum effective 
on the Chicago market (such Chicago minimum now $15.50 per hundred). Any 
packer may make it a condition for the maintenance of the minimum that he 
shall charge any loss through condemnation by Federal or municipal inspection 
to the raiser or shipper. 

Among the packers who signed the agreement are: Western Meat Company, 
San Francisco; Cudahy Packing Company, Los Angeles; Eoth-Blum Packing Com- 
pany, San Francisco; C. Swanton & Son, Sacramento; Armour & Co., Spokane; 
Union Meat Company, Portland; Universal Packing Company, Fresno; Chas. S. 
Hardy Packing Company, San Diego; Hauser Packing Company, Los Angeles; 
Oakland Meat Company, Oakland ; Miller & Lux, Inc., San Francisco ; Wilson & 
Co., Los Angeles; South San Francisco Packing Co., South San Francisco; Moran 
& Co., San Francisco. 

The present urgent demand for increased pork production and 
the assurance of good prices will cause increased effort on the part 
of the regular producers and will bring into the business many who 
have had little or no experience in raising and marketing hogs. 

Therefore, a few pointers are here suggested for the purpose of 
stimulating interest and giving aid to those engaged in the business. 



ON FEEDING, CARE AND MANAGEMENT 

Little capital is required to produce a few hogs and the profit 
comes quickly. 

There fa a place on every farm for at least one sow and her pigs, 
because there is waste feed that they will consume. Preventing waste 
and producing pork is doing double service. 

Careful Management and feeding of brood sows and pigs is the 
way in which the wise hog grower doubles his chances of a good profit 
in finished hogs. 

Hogs are good scavengers but don't force them to prove it. Give 
them a chance to prove it. 

Raise two crops of pigs a year. It is a common practice in eastern 
and central states. California conditions are more favorable than 
those of the east for this practice. 

Use the best boar that you can secure. 

Have the sows in gaining condition but not fat at breeding time. 

Feed the pregnant sows well but don't get them too fat. Liberal 
feeding of alfalfa haj r , alfalfa meal, or wheat bran, with some grain, 
helps to prevent over-fatness, furnishes protein, saves grain, and 
keeps the bowels in good condition. 

Plenty of exercise helps to prevent excessive fatness in brood sows, 
keeps the boar in good condition, and assures good growth in well-fed 
pigs. Arrange pens, feed troughs, and sleeping quarters so that 
some exercise must be taken. Hogs on pasture usually get plenty of 
exercise. 

Provide clean, comfortable quarters for the brood sow, especially 
at farrowing time. Individual houses are cheap and handy to move 
about. (If you want plans write to the Agricultural Experiment 
Station, Berkeley, California.) 

Arrange to have the sows farrow early. The early pigs usually 
have the advantage of a better market. 

Give sows that are suckling pigs plenty of milk-producing feed. 
The cheapest gains are made by young pigs. 

Feeder pigs can usually be raised cheaper than they can be bought. 

Make a creep or separate pen for the pigs that are about three 
weeks old. They are then ready to eat some solid feed. A mixture 
of ground grain and wheat middlings, made into a thin slop with skim

milk is one of the best. Avoid barley hulls, oat hulls, bran and rough 
bulky feeds. Ground oats and barley are good if the hulls are sifted 
out. Do not over-feed but feed often, say three times a day, just 
what they will clean up. 

Save the best gilts and breed them to a good pure-bred boar. This 
is the best method of building up a good producing herd. Keep the 
sows that prove to be the most profitable producers. 

Boar pigs which are intended for market should be castrated while 
they are small, usually before weaning. This is the easiest way and 
is best for the pigs. 

Indian corn is the best fattening grain for hogs. Barley, milo, 
and kafir are 90 to 95 per cent as efficient as Indian corn. They all 
need supplementing with a protein feed. 

Tankage, wheat middlings, cocoanut meal, linseed meal, soybeans, 
skim milk and buttermilk are some of the best protein supplements 
to use with barley, milo, corn and other low-protein grains. Of the 
forage crops, alfalfa, clover, soybeans, cowpeas, and rape are the best 
for supplying protein. 

Barley, wheat, rye, milo, kafir, and other small grains should be 
ground or rolled. Soaking serves the same purpose with barley, 
wheat, and rye, but is not so good with the sorghum grains. 

Soaking ground grain is unnecessary. Fresh slops are usually 
safer than those which have stood for some time, especially in warm 
weather. 

It doesn't pay to cook feed for hogs. In many cases the feeds are 
made less valuable. Potatoes and beans are, however, improved by 
cooking. 

Pumpkins may be grown as an extra crop. They are fine for 
brood sows suckling fall litters. 

Forage crops cheapen production. Alfalfa, clover, rape, soybeans, 
wheat, barley, and rye pastures are some of the good ones. Alfalfa 
ranks at the top. 

Pasture crops give the pigs a good start but it takes grain to finish 
them. 

Young growing pigs should never be forced to live on pasturage 
without grain. Give them at least two pounds of grain for each 
100 pounds body weight. 

Alfalfa pasture saves from 15 to 20 per cent of the grain for 
fattening hogs. It saves a great deal more for brood sows and young 
breeding stock. 



Feeding alfalfa hay in racks is good practice when the pasture is 
gone. Try this for the brood sows. Fee* cattle and sheep the coarse 
stems left m the racks. Nothing is then wasted. 

Afalfa meal fed to breeding hogs helps to save high-priced grain 
Don't force them to eat too much of it. It is bulky and hard to digest. 
One-fourth to one-third, by weight, of the ration is about right. 

Don't feed milk from tuberculous cows. The percentage of hogs 
condemned is twice as high in California as in eastern states. Boil 
the milk if you are not sure. Help get rid of the tuberculous cows. 

It requires five or six pounds of skim milk to equal one pound 
of grain for hog feeding. Whey is worth about half as much as skim 
milk. Buttermilk not diluted is equal to skim milk. 

Sour skim milk gives the same results as sweet skim milk in hog 
feeding. 

Skim milk has its highest feeding value when fed in limited quan- 
tities with grain or mill feed. Three or four pounds of skim milk to 
one pound of grain is the best proportion for shoats. Four to six 
pounds is better for small pigs, as they need more protein. 

The hog is the cheapest producer of animal fat. Don't send him 
to market in thin condition. It doesn't pay. 

The most desirable market weights are between 200 and 250 
pounds. Good hogs should be ready for market at these weights when 
six to eight months old. 

The most profitable gains are made by the young pigs. It pays to 
give them a chance to get to market early. 

A well-filled self-feeder and a thrifty shoat make a combination 
which is hard to beat for quick returns, large profits, little labor and 
diminished risk. 

Don't be afraid to turn a hungry pig to a self-feeder. He may 
make a hog of himself, but it won't hurt him if he is intended for 
market. 

Self-fed hogs should always have an abundance of good drinking 
water if best results are desired. This rule applies to other hogs as 
well. 

Tankage and wheat middlings are the best protein feeds to use 
with the grains in a self-feeder. Cocoanut meal may also be used 
with success but it is not so palatable as the other feeds. 

Self-feeding breeding hogs is not a good practice unless the feed 
is made bulky enough to insure a limited consumption of grain. 



Alfalfa meal may be mixed with grain for this purpose, but it usually 
does not work well in a self-feeder. 

Good thrifty pigs weighing from fifty to seventy-five pounds may 
be made ready for market in ninety or one hundred days if fed the 
self-feeder way. 

Salt should be either available at all times or given once or twice 
a week. Feeding salt with the charcoal mixture is a good plan. 

ON DISEASES AND PARASITES AND THEIR CONTROL 

Eliminate the lice. Lousy hogs waste valuable feed. Crude oil 
applied to the backs of the hogs with a brush will kill the lice. Dipping 
or spraying with a coal-tar solution and repeating in eight or ten days 
is another method. (Use a good brand of coal-tar stock dip. Direc- 
tions for making solutions are usually printed on the containers. A 
2 per cent solution is about right.) 

Keep the sleeping quarters clean and well disinfected. Burn old 
bedding or immediately haul it to some place where the hogs cannot 
reach it. Spray quarters with a 3 per cent coal-tar solution. Lime 
is also good if scattered about the lots and pens. 

Keep lots, feed troughs, and watering places in sanitary condition. 

Get rid of intestinal worms. The following remedies are good: 

1. Turpentine is a common remedy and is easily obtained. Dose, 
one teaspoonful for every 80 or 100 pounds live weight. Give daily 
in milk emulsion for three mornings. Mornings are best because the 
digestive tract is nearest empty at that time. Follow with a dose of 
castor oil. 

2. Withhold all feed and water for twenty-four hours, then give 
each pig one to two ounces of castor oil to which has been added oil 
of American wormseed as follows : Pigs weighing less than 50 pounds 
one-half teaspoonful ; pigs weighing from 50 to 100 pounds one tea- 
spoonful; large hogs, two teaspoonfuls. 

3. Santonin, three to five grains, calomel, five to eight grains for 
each hundred pounds of live weight. For small pigs give the large 
dose per 100 pounds. For pigs weighing 100 pounds or more, give 
the small dose. Mix with morning feed. Better results are secured 
if a few hogs are treated at a time, because of a more even distribution 
of the drugs. 

Prevent worms and disease by keeping the hogs in a good healthy 
condition. Keeping their surroundings sanitary is the best method. 



6 

Conditioners are also beneficial. A good conditioner may be made 

as follows : 

Charcoal % sack or 1 bushel 

Wood ashes % sack or 1 bushel 

Salt 8 pounds 

Air-slacked lime 4 pounds 

Sulphur 4 pounds 

Pulverized copperas 2 pounds 

Mix and put in self-feeder. Allow the hogs free access to the mixture. 
At least, give the hogs charcoal, ashes, and salt. 

If the pigs have thumps reduce their feed and give them more 
exercise. Prevent thumps by plenty of exercise and careful feeding. 

When the young pigs scour, reduce the sow's feed. If they are 
running on grass, shut them up for a few days. Keep the beds and 
pens clean and dry. Let in plenty of sunshine. 

If the sow is feverish give her two or three ounces of castor oil. If 
the pigs continue scouring, give them one to two grains of calomel 
followed with one-half ounce of castor oil. A few drops of laudanum 
may be used in acute cases of scours. 

Good feed, exercise, and sanitary conditions constitute the right 
mixture in preventive treatment. Preventive treatment is the right 
treatment for scours. 

Don't feed soured grain feed or let feed sour in the troughs. It 
causes digestive disorders and scours, especially in small pigs. 

Vaccinate against cholera. It may keep you from losing faith in 
the hog business. (For hog cholera serum and virus apply to the 
Veterinary Division, University of California, Berkeley, California.)
